Pharmacological properties
Pharmacodynamics
The active component of Tabex tablets is the alkaloid cytisine, which has a cholinomimetic effect. This compound increases blood pressure, activates the ganglia of the autonomic nervous system, promotes the production of adrenaline from the adrenal medulla, reflexively stimulates the respiratory center.
Despite the great similarity in the mechanisms of action of cytisine and nicotine, cytisine has a higher therapeutic index and is less toxic. As a competitor, cytisine inhibits the interaction of nicotine with receptors that are sensitive to it, which causes a gradual decrease and complete disappearance of nicotine (tobacco) addiction.
Pharmacokinetics
Pharmacokinetic studies of Tabex in humans have not been conducted to date. Animal experiments have shown that cytisine is absorbed from the gastrointestinal tract at a high rate, but only partially. The degree of resorption of the substance after oral administration in mice was 42%, and in rabbits - 34%. The maximum concentration of cytisine in the blood was reached in mice after 2 hours, and in rabbits - 35 minutes after ingestion. The drug was mainly accumulated in the adrenal glands, kidneys, and liver.
When administered intravenously (iv), the half-life of cytisine from the body of mice is 200 minutes. When Tabex is taken orally, 18% of the dose in mice is excreted within 24 hours. In rabbits, the half-life after IV administration is 37 minutes.
